80 POINTS!!! ALL PLATO USERS: asap!!!
Crank

This year course engages students in becoming skilled readers of prose written in a variety of periods, disciplines, and

rhetorical contexts and in becoming skilled writers who compose for a variety of purposes. More immediately, the course

prepares the students to perform satisfactorily on the A.P. Examination in Language and Composition given in the spring.

Both their writing and their reading should make students aware of the interactions among a writer’s purposes, audience

expectations, and subjects as well as the way generic conventions and the resources of language contribute to effectiveness

in writing. Students will learn and practice the expository, analytical, and argumentative writing that forms the basis of

academic and professional writing; they will learn to read complex texts with understanding and to write prose of

sufficient richness and complexity to communicate effectively with mature readers. Readings will be selected primarily,

but not exclusively, from American writers. Students who enroll in the class will take the AP examination.

Given :

Chlorine's 3p sub level has 5 electrons in it.

To Find :

How many electron(s) more in the 3p sub-level to make it stable.

Solution :

Electronic configuration of Chlorine is :

[Ne] 3s² 3p⁵.

We know, p-orbit is stable with 6 electronic.

Therefore, to stable p-orbit 1 more electron is required in 3p sub-level.

Hence, this is the required solution.

Calculate the percent dissociation of 4-chlorobutanoic acid C3H6ClCO2H in a 0.54mM aqueous solution of the stuff. You may find s
GrogVix [38]

Answer: The percent dissociation of 4-chlorobutanoic acid is 21%

Explanation:

The dissociation of weak acid is shown as:

C_3H_6ClCOOH\rightarrow C_3H_6ClCOO^-+H^+

          cM              0             0

         c-c\alpha        c\alpha         c\alpha

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

Give c= 0.54 mM = 5.4\times 10^{-4}M and \alpha = ?

K_a=3.02\times 10^{-5}

Putting in the values we get:

3.02\times 10^{-5}=\frac{(5.4\times 10^{-4}\times \alpha)^2}{(5.4\times 10^{-4}-5.4\times 10^{-4}\times \alpha)}

(\alpha)=0.21

\%(\alpha)=0.21\times 100=21\%

Thus the percent dissociation of 4-chlorobutanoic acid is 21%
